tam ing machines and has re erence to the emp oyment of a series of plungers, each slidably and resiliently mounted in a casing or sleeve, each sleeve near its u per end being pivotally mounted u on a link to receive actuation from rotatab e crank-shafts, the bottom of the plungers adapted to have removably secured therein any desired cutting or tampinghead; and the invention includes certain constructions and arrangements of frame work and mounting of mechanism thereon found to be useful and convenient.

The novel features of the invention are.

fully described herein and in the appended claims, and illustrated in the accompanying drawings, wherein,

Figure 1 is a vertical, side view of the invention, a part of the escape-way or crosstrack being broken away. Fig. 2 is a plan view of parts shown in Fig. 1, a part of temporary rails or tracks 57 bein removed, and Fig. 3 is a vertical end view of the invention. Fig. 4 is a broken-away plan view of a supporting-bar, one of the horizontal and slidable' rack-bars being shown with brokenaway web, the corner post of the inner frame being shown in section. Fig. 5 is a side view of the arts shown in Fig. 4, the corner post of the nner frame being broken away. 1* igs.

6, 7, 9, 10 and 11 are vertical side views of tamping or cutting implements used in connection with the invention. Fi 8 is a sectional view of one form of the s eeve or casing, mounted upon a link to receive actuation from a crank, the slidable, resilientlymounted plunger being partly in section. Figs. 12 and 13 are plan views showing, respectively, webs 47 and 49. Fig. 14 is a somewhat similar viewto that shown in Fig.

8, but reduced and broken-away; it is introduced to illustrate a modification of theform of the sleeveor casing 8.

Referring now to the drawings for a more particular description, numeral 1 indicates a plunger having a head 2, a shank 3, the latter being provided with a longitudinal slot 4 therein and formed with an opening 5 at its bottom to receive any convenient pounding,

tamping or cutting-head or im lement, as indicated by numerals 6, secure to the shank, as by key 7.

A GflSlIlg or sleeve is indicated at 8 and is formed with an opening of a diameter substantially equal to that of head 2, and of a less diameter than the shank of the plunger, that the coiled spring 9 may be seated within the sleeve between the walls of the shank and sleeve. The lower terminal of the sleeve is inturned or projected inwardly to,approach the surface of shank 3, thereby forming the detaining-head 10; I provide the enga ingpin 11 secured transversely and central y of sleeve 8 to traverse slot 4 and limit the outward movement, of the lunger; spring 9 may have bearings upon [I]. 11 and head '10, and the parts thus name may be said to describe a tamping-member A. The upper terminal of sleeve 8 is formed or operates as a socket 12 to receive the head 13 of link 14, this link having one of its ends pivotall mounted therein as indicated by pin or bo t 15. I provide crank-shafts 16, provided with cranks 17 formed thereon to extend alternately from the shaft, in op osite directions, and heads 18 of links 14 have pivotal mountings upon each of pranks 17.

By reason of the arrangement described, the arts may be constructed of any desired thickness or solidity to Withstand the high degree of vibration incident to their uses. It is intended that the plunger will be driven upward at each downward stroke of the crank when implementfi strikes upon an obstruction, the force of the concussion being received upon spring 9, at which time the forceof the blow will be communicated to pin or bolt 11 and head 10 of the sleeve, head 2 of the plunger at this time having a limited u ward sliding movement within the sleeve. T 1e modified form for the sleeve or casing shown by Fig. 14 is considered preferable for heavy construction Work, its upper end having a wall 8 of greater diameter, and therefore heavier, than its lower end 8" For use of the parts above described, in road-bed construction for trackways, I employ thev same in connection with certain framework, mechanisms and devices now to be described, and best shown in Figs. 1, 2 and 3.

Numerals 19 indicate car-rails or a trackway supported upon ties 20, and for the purmaterial is used for a road-bed, I construct the angular, outer frame 21 having bottom plates or sills 22 at its sides, these sills being secured in any convenient manner transversely and rigidly upon platform, 23, the latter being preferably boxed or apertured to receive axles 24; and wheels 25.are used in connection with axles 24, said wheels resting upon track or car-rails 19, and I employ braces 26 each, secured at its lower end upon an outer end of the platform and adjacent one of wheels 25, said braces passing inclinedly upward with their opposite ends secured u on a side of the outer frame, and

as thus escribed, the platform and parts supported thereon may be moved any desired distance along track '19.

I construct the inner angular frame 27 containing several devices presently to be described, the wei ht thereof being sustained by frame 21. I provide vertical racks 28 formed upon the outer face of each corner post 29 of the inner frame, and said racks ave engagement with pinions 30 secured upon the horizontal end-shafts 31 of the outer frame; end-shafts 31 have mountings upon horizontal plates 32 which connect corner osts 33 of the outer frame with the vertical side-plates 34 of said outer frame, near the front and rear of the machine; the a horizontal plates 32 rovide adequate mountings for the end-sha ts, and are shown in the drawin (Fig. 1.) as artly broken away, that ot er parts 'may e shown. Shafts 31 are geared to rotate in unison by means of connecting-shaft 35- and its miter gear connections, this shaft extending horizontally and lengthwise of the outer frame and suitably supported thereon as by boxings 67 secured upon the vertical side-plates 34.

. By manually rotating either one of ele-,

I vator-wheels 36, pinions 30 will be actuated to cause racks 28 and the entire inner frame to be raised or lowered with reference to the outer frame, since elevator-wheels 36 are mounted upon end-shafts 31.. The purpose .of raising or lowering the inner frame is to adjust the altitude of tamping-heads or im-- plements -6-, that the latter ma make a proper contact with the materia operated upon during the tamping process, at each downward stroke. of tamping-member A; another purpose'being to elevate the outer frame together with platform 23 and wheels 25 a suflicient height above the main track 19, that the entire machine may be temporarily removed from said track 19, by means presently to be described. a?

1 I employ two crank-shafts 16, each mounted in suitable boxings 37, the latter being secured ,upon supporting-plates 38, these plates being secured horizontally and transversely upon side-rails 65 which extend par allel'with and below the top side-rail 66.of the inner frame; said crank-shafts are disposed parallel with reference to each other, their bearings being near a side rail 65, w th-' in the planeof the inner frame; and to actu-v ate the crank-shafts Iemploy any desired .shafts 16, the latter receives actuation to cause downwardly-directed blows to bedelivered by the series of tamping-heads 6, already described.

Crank-shafts 16 are connected to rotate in unison, as by transversely-disposed links 45, these links having their terminals seated upon some of the oppositely-disposed cranks 17 of each crank-shaft 16, and thereby actuation of both crank-shafts will be made from the movement of the sprocket-wheel 44, and upon the rear end of the crank-shafts are secured fly wheels 46, their use being to pre-' vent undue vibration of these parts .during operation.

It is desirable to have control of the movements of sleeves or casings 8 and lungers 3 to effect a vertical movement of these parts when actuated by cranks 17 and links 14, and therefore I em loy two airs of apertured webs which aresulistantially alike except as to size of the apertures; the upper palr of webs 47 are dis osed upon the same horizontal plane and ave apertures 48 to receive therein the upper ends 8 of sleeves 8; the lower pair of Webs 49 are disposed upon-one horizontal plane and have apertures 50 therein to receive the reduced ends 8" of said sleeves, apertures 48 and 50 extending vertically through the webs. The pairs of webs 47 and 49 have substantially equal length and extend practically the length of the inner frame, but upon planes of different altitudes. Apertures 48 are ofa size equal to the diameterof the upper end-8 of sleeves 8 or slightly in excess thereof, and apertures 50 are of a I size corresponding to the diameter of the re duced ends 8 of said sleeves, the intention being to form the apertures to permit a vertical movement of the sleeves therein; the webs have certain mountings and their movements are controlled by means presently to be described.

During operation of the machine and when crank-shafts 16 are rotated; each of sleeves 8 as well as lungers 3 have movements the tendency '0 which is to swing sidewiseof the machine, from actuation of links 14; the webs with apertures .48 and 50 operate as guides'to prevent swin ing of the sleeves and plun ers;1t will be un erstood that lungers 3 wi slide longitudinally within s e'eves' 8 since heads 2 have bearings upon the inner Wall of the sleeves and the bodies of the plungers' have bearings upon the inner walls of detaining-heads 10, but to control the movement of the plungers it is necessary to control the movement of the 'sleeves to revent said sidewise movement, and there ore the apertured webs are employed, and during operation of the machine, while links 14 are actuated with considerable force, their movements are not particularly rapid, and the limited movement of the sleeves orparts of the sleeves when moving Within their guides or apertures, is smooth and vertical; the sidewise movement of the webs must be controlled, as matter, of course, and this will be explained.

Alining-members 47 and 49 are called webs because they areplates or Webs which extend between oppositely-disposed rackbars 51, to which their ends are secured, and, to effect a control and an adjustment of each Web, said rack-bars 51 are em loyed, said rack-bars being slidably seate u on and supported by rack-bar plates 52, t e latter belng secured upon corn'erosts 29 of the inner frame; I employ rac -bar shafts 53 havings'uitable bearings upon arms 68, the

latter being secured upon corner-posts 29 or constructed integral therewith. Shafts 53 extend parallel with the webs and their bearings are above and adjacent rack-bars 51, the latter extending transversely of the inner frame. Shafts 53 are provided with wheels 54 secured upon their rear ends, and with pinions 55 which-engage rack-bars, 51; and b manually rotating Wheels 54, pinions 55 wi 1 cause a transverse sliding movement of these rack-bars, and thereby the webs, or any of the webs, may be moved transversely and horizontally toward the middle or sides of the machine. Pinions 55 are geared with rackbars 51 so that a rotation of a shaft 53 will cause the rack-bars to move in unison upon that shaft, and therefore the webs and a ertures are reserved arallel with the mac ine and with the cran -shaft 16 With which it cooperates. ment which maybe im arted to the Webs, as

above described, it wi be understood, that blows made by heads 6 may be deliveredupon lengthwise space of the road bed, and this is the function discharged by the webs. Since the apertures of any single web are in longitudinal alinement sleeves 8 and plungers 3 Will be controlled by that web to remain in.

longitudinal alinement, and when the ma- -chine is in operation, tamping-heads 6 will deliver blows in a corresponding line across the space to be constructed.

Since the pairs of webs 47 and 49 are upon dlfi'erent horizontal planes, a control of the movement of casings'or sleeves 8 is more readily made to confine said sleeves to a vertical movement. The verticaldistance which sleeves 8 and plung'ers 3 will move at each ro- By reason of the lateral movetation of crank-shaft 16 depends, of course, uponthe' length of'crank-arm 17, and only a limited distance is" required: Since the plungers are resiliently mounted, vibration is much reduced. Implements 6 maybe of any desired shape, and in practice, sets of implements are employed of different lengths, as may be desired.

Since the inner frame 27 is vertically movable and under control, it may be lowered su'lliciently to cause heads 6 to reach the lowest position between the ties or to reach the bottom of a road bed, and the inner frame may be readily elevated for tamping material at higher altitudes; and when one part of a trackway has been completed the machine may be moved upon track 19 to any unfinished part.

When used in connection with railway construction, it may be desired to remove the machine from track 19 temporarily on account of passing trains, and therefore a crosstrack or escape-way 56 is employed, consisting of rails used in pairs, upon which the machine-wheels 69 mounted upon the lower parallel side-sills of the inner frame may rest; a pair of temporary rails is placed crosswise of track 19 to occupy a position below machine-wheels 69, as temporary, rails 57, shown in Fig. 1, and by manually rotating elevator-wheels 36 the inner frame will be Weight of the entire machine resting then upon the machine-Wheels 69; one end of the pair ,of rails 58 is then secured to the ends of rails 57, as by hooks 70 of the rails of pair 58 passing within aperture 71 formed in the ends of rails 57, or by anyother convenient means; and to the pair of rails 58 the pair 59 may, in like manner be secured, and the pair of temporary rails 72, may also be used; supporting-posts 60 are em loyed, these posts being constructed of di 'erent lengths, and provided with o enings 61 formed therein; the pairs of rai s mentioned, when placed end-to-end have a combined length, as a trackway, suflicient to support thereon the entire machine, and the temporary trackway may be adjusted to a height practically upon a level with track 19, and this temporary trackway may be supported upon an ordinary railway embankment since posts 60 are of different lengths; bolts 73 are used to register with openings 61 of posts 60 and o enings 74 of the temporary rails to secure t ese rails at the desired altitude. Horizontal alining rods 62 are used between each of the rails of each pair to secure e iii-distanced and after the machine has been moved from other crank-arms could be employed and exably supported outer frame, an inner frame track 19, rails 57 are removed, that there may be no obstruction to a passing train.

By the arrangement just described, the temporary trackway may be readily placed in operative position, and afterwards may be disjointed and placed upon platform 23 where it is carried, when not in use. Since implements or heads 6 are employed in sets, and the lengths of the shanks of these sets vary, when temporarily removing the machine from the main trackway, these heads or implements may be removed, if desired or if obtrusive.

Having quite fully described function of parts, operation of the machine will be understood. When in use upona railway road bed, the machine may be moved upon wheels 25 upon trackway 19 to any desired point. When used upon a highway or for street construction the temporary trackway 56 may be useful for moving the machine to a conven-. ient osition transverse to the direction of whee s 25.

Crank-arms 17 are shown oppositely-disposed upon crank-shafts l6 and this is the desired construction, but it is considered that tended radiallyfrom the'shaft, without'departing from the scope of the invention.
